House M.D

Lets start.
First of all those 2 sides are abit too far away and they look abit far from each other.
text is too small and the placement doesent goes well at all.
those 2 colors on the background dont fit.. i know the render has those colors, but if you could blend them both it would look much better.
Dont forget about the main effects that help your tag look way nicer.
i mean about filters/color balance/exposure/hue etc. you know, use them.
Overall i wanna see your next work, considering my critique.

i can see the flow in here bro !
needs more depth ! light is good but text needs work

and do what zenie said...and post it here ! good luck on it
