I liek it too much , try to erase part of the pentool, it will blend well. There is some random over-sharpen parts, try to blur it.
I think if you used mroe pen tooling it would look cool. When using a render, try making a BG first, then adding the render and add effects affter. IDK Not bad overal.
Well, i usually base the flow out from the render, so i like adding the render first, also i usually use the render as the focal, so its kinda hard not to add the render first xD. Thanks anyways.
I think that the render should be blended in a little bit more, and the text doesn't look that good either. Good job anyway.
