You're really talented - I'd never be able to do that in photoshop if my life depended on it XD Thanks for sharing the beautiful artwork
It's pretty good; my only real criticism (as someone who also plays with Photoshop) is that your edges are a bit choppy in places. I dunno if that's what you were looking for, but it might just be my personal preference to have everything nice and smoothed off. You could fix that by just taking the blur/smudge tool to the edges though, or apply a blur to the whole picture or something. Though I dunno how much you actually use Photoshop and if that's something you care about. Regardless, not bad.
Or check the 'Anti Alias' box when selecting something, so it smoothens out the edges automatically. Seems like you forgot to do that if you want them to be smooth of course. But not bad indeed
