I'm gonna try to say this in a way that.. Is as non - dickish as possible..
All I see in these videos is you piling a bunch of flares and lighting effects onto something that somebody else has made. I'm not saying they don't look good, because they do, but all I'm saying is I'd like to see you branch out a little and start trying something new. In all 3 of these videos I see you use the same lighting effects, and flares. Add more to some of your art, and delete some things for some of your art. For example, the last video, you did almost nothing to the picture itself, (Just saying what I saw, I don't know if you did do a lot, and I just couldn't see it or what,) all you did was add shading, and once again.. The same flares.
Start doing new things, because none of us want you to get stuck up on yet another style for 2 years. When you find a style you like, use it, but don't overuse it. Start combining your styles of art together, and then I'll start to like your work more, but as of now it's just a bunch of flares and effects piled onto a premade graphic.
Also, start trying to add different colors, not just a couple. I.e, the dead space and frog monster speed art's, you are focused all around one color (mainly) try adding more colors that compliment each other.
I'm not saying you should take any of this advice, for all I care you could throw all I've said in this post away, I just want you to take some things into consideration.
Holy shit.. I'm impresed Seyeko. You started doing some detailed work with the renders and you started editing it, and actually doing some things in your own.
I love just about every part of this except I would've love to have seen the Background have a little blur to it, and other than that I think this piece really turned out great. I loved the way you did the text, and it really just looked good and had an overall nice feel to it.
