...too simple imo. a banner should have MUCH BIGGER TEXT!!!! it shouldn't stand out through colour like that. make it BIGGER! and make the colours match a little more.
and i dnt like the renders........mind u the best bit on the left one is actually the bit u edited

(the bite out of his leg...its amazing ^ ^) the right one is pretty crap though......its not a very good quality render....whoeva made it....either that or it just doesn't fit in with this banner at all. outline is too visible.
but ye...seriously needs bigger text. and a darker colour. bright red is too strong and red is a bad choice of colour if its the only colour in the text...like here (advice my mum once gave me.....and shes an ex-graphic designer so ye...shed know this sorta thing)
