I'm a highly skilled pixel artist, and your arcade game project sounds fantastic! I can create the 32x48 px 16-bit tennis racket and hand sprites idle, hit, hard hit exactly as you've described, perfectly matching the upright, face on perspective from your screenshot. Here is my portfolio: I'm confident I can deliver this with the high quality you need. I've also sent you an email with the same details. Looking forward to potentially working with you!
