Oh, I can field this one.
The first picture you uploaded was by Cross-chan, who removed it from her own gallery for a reason. The second was Western art not drawn by you. Neither is permitted. No harm done, mistakes happen. It's my fault for forgetting to contact you. Just review the site rules again before uploading. This thread here may be helpful as well:

EDIT: They certainly did show up, for what it's worth, so I suppose the test was successful. Be more careful about what you upload in the future, that's all.
