Thank you, I'm glad you like it.
Correct me if I'm wrong, but it's 64x64. I edited and re-uploaded the images just in case. 100x100 for prev and 64x64 for main art. Hopefully it's correct now.
Please check again, if you still find it doesn't fit, I'll delete it and resubmit my submission.
Looks awesome, but one of the challenge rules is 64x64 canvas. You can leave the big one as preview but please try to crop the main art to make it count towards the weekly.
Yes, it's all good. The main art is indeed 64. Do not delete it, you already have ratings and you would lose them then :)
