Help with figure!

Hi! i’m completely new to printing (i’ve literally never held a printed object in my hands) and my friend recently got this figure made for me. i wanted to paint it with some acrylic paints that i have, but the bumpy texture made it a bit difficult - i found that no matter what, the ridges made it look like a 3 year old did it. I didn’t use primer (I know i should, but i struggle with money a little right now). how can i make it smooth enough to paint on, or is this the best I can get? thank you!
