take out the border for one, dont use such borders they are bad for a tag, you can add borders but then use top and bottom or sides only... and then do them 2 or 3 pixel width, not 1 pixel, also agreed on the fact that is lacking dept and fx, easiest way to create dept is adding renders/c4d's or other things in the bg and blurring them, or using stocks....
to create FX, you can also turn towards using c4d's on lighten or linear dodge.. best are bubble c4d's or fx c4d's... there should be some resources you could use around here in the resource page I think, otherwise I could get you some links to resources...
you text use is alright though...
so yeah, gj for your 3rd tag, kiu
practice makes perfect-er... and probably check some tuts on some techniques and such... on how to create dept and more...
Depth.
--------------
Depth is really lacking atm.
Try to use some c4d or brushes to create a more indepth view to increase depth.
Also try to make the center of the render higher than the effect. This will also help create visual depth.
Lighting is also a good way to add depth
--------------
Flow
--------------
Not alot of flow but the flow that has been added works well and matches with the render.
Again as stated before when you create more depth flow will also normally increase due to the building of depth by most artist.
-------------
Blank Space
-------------
There seems to be alot of blank space not being used.
Because of the lack of effect centering the render would have helped.
