Well let me be the first to welcome you then! 👍
I think that part of the reason might be to do with the size of your pictures - they are massive! I'm lucky, I have a 24" display (and fast broadband), but not every one does. 👍
Try sizing them down a little, I use 640x480, or provide thumbnails that link to the bigger picture (Imageshack has an option for this).
As for your pictures themselves, you have some good ones. The first drifting Cobra is very nice. As are the Shibuya Subies (the first is my favourite of that set). I also like the cloverleaf Alfa (I forget the name), but you have put some BMW wheels on it!

The spitfire is nice, and the Volvo estate shots are funny too - its been a while since I saw some one post a drift shot of that car!.
As for some of the other pictures, you didn't save them at 'super fine', and they have an obvious blockyness to them. If you can correct that shortfall, and keep posting your pics in a smaller size, I'm sure that you will get more comments.
Great stuff, keep them coming! 👍
