Cute

Oh wow this was cute and adorable her body form came out very well and you presented some good shine I feel like her expression is off a bit maybe you should have her smile and also have some props in the background more design or some scene would work too

Some background scene or backdrop or some props and have her smile

My Thoughts to spill on this Pinup

1. Design & Style. It looks Good for a Pinup. and it has a good look. (i'd rebalance that teen rating to mature and even then, its debatable to say that in the least regard.

2. Color. I'll say. it looks very good with the color scheme and blends very well.

3. Other Details. Boobs are well ( ͡° ͜ʖ ͡°) and over all the detail in the drawing is well made

In total. I give 5* Its well and styled very well in my opinion

I would hit that
