2 questions:

What´s the meaning of #otp ??
Are you sure that critiques are welcome ?? XDDD I can be a little hard with critiques XD

Anyway thanks for your comment on my last picture !! ;)

CRITIQUE:

Good:
- The faces expressions each other
- The polished and thin lines

Weird ?:
- The hairs have the distance of shades and lights very equal each other
- The mouths are very long, i understand that drawing faces sideway is difficult
- The heads are maybe a little big
- The characters appears a little hide in the corner leaving a lot of space in the opposite corner, i know tha you want to show the text but you can do it a little more small in an elegant drawed paper
- Very simple background with only one color and the text
- The ear should be on a more down possition

Tips to improve: (for future drawings)
- Use a little more unequal distances and sizes on the hairing shading and lights and do these lights more strong and add to the lights a blur layer of white to do an effect of more blur shine
- Correct the proportions of mouths, ears, heads... Ussualy a normal teenager manga body sizes 6 or 7 heads
- Try that the ocs gain leadership doing them more big on the screen (except if you want to show other thing more important than them)
- Avoid one color backgrounds, idk, try with acid or pastel colors combinations or a landscape
- Use more strong shading and you can do it with the color theory of colors that are very near each other on the wheel, example: Brown hair with a little more red and dark shading and a little more yellow and light shines (more details on my manga coloring tutorial)
- Try better calligraphy with the text to do more readable and beautiful to the view and put it for example into a paper with a light of a window illuminating it
- Move the 3D layer of the ocs more near of the screen or slow a little more the slider because when the scene contains too few elements is better don´t use too deep 3D to don´t displease the view. More deep is for more elements layers and a landscape for example

Well... thats all that i can see in a quick view and my english is probably very poor, so, sorry XD

I hope that was useful :)
