Netsu's drawings.

I know it's a bit rough, but I'll get better.

Spoiler:

Actually, quite the opposite. Your idea of color arranging is wonderful, your lines are bold and noticeable, and your concept of imagery is quite amazing.

Beautiful drawings! You'll get much better with more practice. ^^

Thank you so much!

I have a favor to ask of everyone. Please point out on what I did wrong and how I can do better. You can be as nice or as harsh as you want as long as it helps me in some way.

Spoiler:

The overall drawings are perfectly outlined, well bolstered, and your coloring is fantastic. A tip you could learn however, to make the appearance of the Koi explode and beautify, is to shade its fin's and tail, as well as mark small, detailed areas on the scales and eyes.

To shade, all you have to do is pick your color of choice. Recognize where you want the shadow of the image to begin, and the light of the image to end. For instance, if that red Koi is pointing down, the bottom-areas of it would be dark, and the top areas would be lighter than the darker colors at the bottom. Shading is all about shadow perspectives. To shade with tools such as pencils, crayons (I can do it with markers, spraypaint and pens though.), drag your color along, pull off lighter, and then completely pull off once the color seems to "evaporate" into the white of the page. :)

This should help you nicely.
