Fantastic! I like the use of gradients the color choice, the background is very fun and points me eyes at the freaking woman.
Your linework is definitely at its best when its chunky and confident, like with the hands, hair, and glasses. The crotch area gets a little wobbly because the lines are thin, maybe go in and reshape them a bit, it's fine if you can't get it in one stroke especially with your style. I could also see it as lack of confidence in the anatomy which I have issues with too.
I see some antialiasing lines on the clouds and stripes where you fill bucketed them, try to see if yer program has an expand fill slider (clip studio paint does if that's what you use) or it might be antialiasing is on for the fill bucket.
I like the little windows in the corners zooming in on nothing in particular, its weird and unnecessary but charming. Also your logo, very stylish, people never do that kinda thing with their signature, I'm a fan.
Well yeah so like good freaking job bro I love you

This is pretty great, the style is spot on. Great job!
