No worries! Not enough for me to deny entry, but something I wanted to point out! A good rule of thumb (imo at least) is to upload it to the image checking site to make sure you didn't miss anything weird. I've had a submission show up with like 20 colors, tho only actually used about 7 because it was catching some weird invisible pixels. 
I blame my slight color blindness! I was sure that's the same color as her skin. Ty for pointing that out
Ooo this is neat! The hair shape is nice and soft! Good job on this.
This is also a very small thing to point out, but there's a SINGLE dot of darker pink near the eye closest to the viewer. Not really a problem, but something you could remove to lower the color count down to 6.
Again, great job!
I'll make sure to upload them next time XD ty for the advice
