It looks neat, 
Myristavia ! A few pointers that may help you a bit in defining your art style. I might try to find a way to either break up how much bevel/emboss you're doing in photoshop or find a way to hide it a bit. I would also look into colors for your lighting and shading other than white/black. Outside, shadows are typically dark blue, though your eyes will trick you. I also like having a bit of a yellowish hue in the lighting, but that's up to you. All of your artwork is very bright, contrasty, and colorful (which are good things, and not all of them are words...), but be sure to add some fog or something behind the main layer of play so players don't get confused about what they can interact with and what they cannot. Background confusion is a common challenge for platformers, so work on fixing it as soon as possible. It's coming along nicely, though, and I definitely can related to the job + game dev thing (as can many), so keep on pushing through!
