The claw guy from yesterday is the best thing on the page. Very bold and graphic-y; nice clean colors. Transparent color tends to look "dirty" when it's heavily worked. At least, I can't seem to get the hang of it.
I was once on the receiving end of a critique so savagely nasty, I marched straight out of class to the office and changed my major (sketchbook).
This is a nice start to a thread. Lots of mostly realized work with lots of good choices. However, your fundamental drawing skills are lacking, as in your solutions for how the lighting falls on the figure and how the anatomy works, specifically how the musculature affects the visible surfaces and planes.
Start working longer on the beginning steps of the drawings, the linework, the proportions, blocking in the shades in a logical way. It'll go a long way to helping to finish a piece.
Also, spend as much time drawing from life as possible. It's critical.
hey, while I like the claw guy, i have to disagree with stoats respectfully as i think that your still lifes are very well done, the time and attnetion you put into them really shines through, the texture on the orange and apple both are great and so is the lighting
