Many thanks for all the comments on these.
THe light source was window light with a remote flash to the background to seperate me from it. I tried it with a light to the side but results were poor so need to revisit that.
I agree that the second is a little soft Geoff, can't remember what the exif was, but I'll dig it out. THank you for the compliment mate - my portraiture leaves a lot to be desired next to yours. I'd love to get together too and learn some tricks from you.
I actually cropped them like like that purposely, although they were pretty much framed like that. I didn't want them straight in the middle, and also didnt want them too much on the thirds. Thanks for the critique Peter, wouldn't have noticed that they weren't overtly harmonious.
Matt. K, thank you for the compliment as well, but I'm not sure I'm with you on the poster thing. I would feel hyper arrogant and a bit of a jerk putting pics myself up all over the place. Not too sure it would perk up the daily journey into work either for people waiting at traffic lights!
Once again, thank you everyone for commenting. All appreciated.
