Wow, thanks for the tips Mitsuki, I'm still working out what works best for me, I like the idea of having the hand tool on the pen, gonna give this a try.
Here are some more doodles, I am starting to have a serious love/hate relationship with cylinders, but feel I shouldn't move forward without at least getting a little more comfortable drawing them as I see they are used a lot.
So here I was playing with cylinders, for some reason one of them looked like a weird creature, so I ended up making a little doodle of a creature with some contour lines trying to make it look 3d, then I added a scene around it.
Also, one of my cylinders started looking broken with the contour lines, so I ended up really breaking it and then I tried painting it (I probably should have looked for some reference on how the metallic surface would look, but I didn't)
Hope you enjoy
Cheers!
