Thanks for the response!
To give a bit more information that is lacking in my "portfolio" A lot of the content that is posted in there was picked out from a lot of other pieces of work I did as part of the College program I took, which did cover things such as figure drawing, perspective drawings and other introduction to art skills, and were just not post on the linked website because my art teacher at this program deemed them "un-necessary."
I could post a lot more pieces that I've done which would demonstrate my skills further for sure, such as posting my google drive link which does contain a lot of other pieces I've done, which I think may have been the better choice here because as you've pointed out there is some things missing in the examples I do have on the wordpress page.
To answer the questions you asked in this post though here's my answers!
Can you draw yourself in the mirror using just two values: If you mean something akin to what you would do for a half-grisaille painting I haven't done one of these yet but I do plan on doing one of these. I have done some self portraits where all I used was a mechanical pencil and a blending stump at first, then did some acrylic painting behind it to frame the portrait better and I can post that if you would like!
Can you draw 100 perfect cubes with no arbitrary convergence?: I would say yes. Part of the College program I did we did a lot of on paper white boxing, which I've used vanishing points and lines to make sure they were correctly foreshortened and "square" but I can't say I can do it without the guides which I think is to be expected for the most part.
What is your favorite text book?: I think this is probably the hardest question for me to answer, but I think the one I like the most would probably be Colour and Light by James Gurney, albeit none of the examples I have posted would demonstrate the things I've learned from that, since I only recently started applying it to miniature painting as I've been trying to come to understand colour and form a little better.
What was your favorite master to study: Leonardo Da'Vinci is for sure my favourite classically trained master and he's the reason why I wanted to take up art when I was younger. Outside of Da'Vinci, I think I would say my favourite master is Anders Zorn. I also really admire gothic sculptors, just not one specific sculptor.
Who is your favorite artist: In modern digital artists I would say I do like the works of well, Marc Brunet, Paul Kwon, Adam Duff, Anthony Jones, Akihiko Yoshida and Hideo Minaba to name a few. I can't really pick one of them to say they're my absolute favourite because there's elements that they all do that I love, but if I had to choose from that list I think I would have to pick Adam Duff because his artwork tends to really lean into the gothic horror look I personally enjoy.
Thank-you for the brutal honesty you've given, and I wouldn't consider you being an asshole for it since I did ask for harsh critique after all!
The pixel art was more so because of game projects I had to do while pursuing my degree, and while I do like it I'm personally more of a fan of 3D works, hence why there's also a bunch of (albeit not great) 3D models as part of the website!
If there's any more questions you have that you can think of that would help you better gauge where I am, feel free to ask them of me and I can even supply you with a more trimmed down version of what else I've done in a google drive or something like that
