I want to try with different medium, so that's it. Thanks for your replys ^^
These are very nice. Are these pastel? Were they all done from models? You did a great job of capturing the facial expressions.
I'm a fan of lost edges so #2 portrait appeals to me...
I think you also challenged yourself with angles and subject matter that can be a bit daunting, such as the teeth (especially in profile) and the extreme perspective of the third portrait. I also like your choice of colors. They fit well and add en emotive quality to the pieces.
I would have liked some of the shadows in the first portait to be a bit cooler and/or contrasting, just to add a bit more depth and interest. But, that is a judgment call.
