Its not bad, at all, i really like what u are trying to do there

tho pic looks bit lq , if u resize it that way, always press and hold shift while resizing, otherways it comes out very lq :S
about c4d , i think u should place them more around the face, not really on it, try them look round, so they blend on it, by erasing some with soft brush, then try add some gradient maps, to make colours mach with each other more, blend all the picture together

and maybe try make new layer, put it on overlay, and with big 100 or 200 soft brush collour some lights with it, and creat lightening by >new layer > apply image >filters>render>Lightening.. change options u need :> and voila, sig will be outstanding!
hope my tips will be usefull

nice art work there friend
