RAIN: Isaac sketch

Isaac, my OC in my story, RAIN, that I'm never getting to....The title sounds so cliched and stupid, but it also sounds so cool!

It's crappy because I'm sad that my SAI trial ran out.
Recently, I like abusing textures and gradients; so yeah. I have to use overlays!! *is shot*

I personally like the current one better, because it gives that rainy-day vibe, but whatever, what do you guys think?
