The male arm seems out of place and awkward, either have the right arm in his pocket or use an arm pose similar to chili's

The female's hand seems weird, as if the pokeball will roll out f her hand, try looking at how red and blue's hands are, and how they each hold the pokeball to get an idea of how her hand should look - furthermore, her bag looks flat and has minimal detail, something similar to Rosa's bag should do fine, perhaps even her arm pose as well





Overall they look amazing, a major improvement from your previous characters, and the only real copy is the had from Brendan, but most ski caps look like that, even from Pokemon, and to be fair that is the only part that really looks like him - Great work, I hope to see more awesome pics
