The lighting and processing on #1 is...just awful. Awful. And that OOF shirts and tie as such huge elements? Sorry, I realllly dislike this concept and execution. The skin tones are whacked as well...
On the other hand, shot #4 brushes with greatness. I think it's a bit too darkly-rendered in processing, but the lighting and overall "look" is a very classic color studio posed portrait image. Shot #5 has the same rich, saturated color look; on both #4 and #5, I think the degree of saturation and vibrance is a little too high, but looking at these, I think you could process them for a bit more digital fill, and a little bit brighter blackpoint.
What I really do not like about 1,2, and 3 is the incorporation of raw, specular flash accent lighting: I know how it is done, and have seen it done since the 1980's. To me, it looks noobish. I want to see that kind of accent light done expertly, with a grid and a diffuser over the flash, so the light is not "raw light" that looks blue...grid + diffuser + barndoors is my recipe for this. I actually have an entire system dedicated to this light...it's an 11.5 inch , 50-degree beam spread, deep metal parabolic reflector fitted with either a 20 or 35 degree grid and 1,2,or 3 mylar diffusers, + a 2-way barndoor, so the light looks very subtle. That is impossible to do with a speedlight unless you go to a lot of hassle.
Shots 3 and 4 forego the "I'll aim a speedlight at him" lighting scheme, and skip the unneeded accent light, and that's why I like them much more than the other three images. The lighting is understated, and simple, and the subject just naturally advances in a dignified, three-dimensional, glorious way. #4 has a gorgeous Rembrandt-style lighting scheme, and except for the deep dark shadows and heavy blacks, looks awesome. Shot #5's accent light is very small...so,so subtle, and yet, it's a little blue, but I don't care--it's so small, and yet it helps so much. I like the skin tone rendering on #4 and #5..
That's not a wound above the eye...he's had that since he was born...for a first effort, this is a pretty good result. We've all seen much worse.
