Welcome to Gaia! ::

nice I like the way that you used the 3/4th's rule in your portrait photos... they really came out nicely.

In terms of techniques you've got some really nice camera subjects, I especially like the car photo... very interesting. I think you could possibly make your images more dynamic by adding small camera tilts, and then cropping them in Photoshop, or using masses of colour composition like the orange and red with your fire vs the dark (example a mass of black with a small amount of colour directing our attention on the colours, or vise versa? ). Just little things like that, that could take your photography a level higher. But other than that, they're very nice photos : ) you did a great job! Can't wait to see more from you in the future : 3
