Good sketches
Ok well this here is decent for sketch work but you really could add more in terms of the Sailor Moon universe. I love the use of character representation in this. You have Usagi down pretty well in her ditzy ways and cute nature with strong body language and facial expressions. Just try to use the drawings in a setting like a battle or maybe a moon background with just one of the sketches as the main art. Good line work and coloring too btw. I do think you have some talent here. The lines do need a bit more solidity to them and refinement but good job nonetheless.
~~THINGS TO IMPROVE ON~~
As stated above. Keep it up.
