Hey, great work on the 3-point perspective assignment, it really shows that you put in time and effort to set up an interesting scene.
I have little to say in terms of critique of your perspective, which is consistent and accurate throughout the whole piece. Kudos for that! I think the one thing you could improve as a next step is not your perspective, rendering, or composition, but instead building a wider array of reference pictures when composing a piece.
By this I mean looking up references of castles, cathedrals, gates, and so on, and maybe even researching the history and purpose of architectural elements.
- Square vs. round towers? Typically they're separated by a few centuries if they're on the same building
- Round vs. pointed/gothic arches? Also not from the same time-period, and can be remarkably complicated in terms of stone work.
- Flying buttresses or simple wall buttresses? Why are they there? Are there enough along a wall? too many?
- Bricks or masonry? Are the slabs chiseled out of rock, or combined through brickwork? Are there decorative elements or is it completely barren?
- Scale, design and spacing of wall crenellation, logical position of machicolations?
- etc.
To make up for limited research time when constructing a drawing, references are key! To build anything from imagination is really hard, because you really need to master the subject in order to avoid mistakes when inserting details, in this case medieval defensive works and architecture. Very niche stuff!
Once again, great piece, and looking forward to more of your work 
I hope I'm not a downer or anything, I think you're on the path to greatness and this is the best advice I could give from looking at your piece! Cheers!
Today I decided to model a character on Zbrush I decided to model Aku Aku from the crash bandicoot series. I decided on this character as it would be a good practice as it is simply made of basic shapes.
Clothing and drapery practice for term 3. Sorry about the wonky faces the study is mainly for the clothing. Any feedback is welcomed, thanks in advance.
Not sure what the elves should look like face-wise, but maybe give more volume to the neck muscles?
Some more clothing studies, for some reason i find white clothing a lot more easier to paint than black/darker clothing.
Think I'm getting the hang of clothing a bit more than I did last week. Got some tips from Marc from last live Art school session mentioning how I should boost the overall contrast of my folds.
