Hi George,
Thanks for the reply and pointers.
This portfolio was actually updated with stuff I did for a company some time after Stan wrote his reply. Before that, I didn't really feel I could use those pieces on my portfolio, because a) I didn't get permission to use them (on that note, I probably should take them down now - I only put them up because someone specifically asked to see them) and b) it was not representative of what I am able to do at home with my current set up.
When I worked for my last company, I had all manner of models, textures and other tools whereas now, I don't even have MAX and vRay. I'm essentially having to learn new software from scratch.
Out of all the images on the website, only the house exterior (very first image), Luna Grill food stand, bedroom, kitchen and everything in the 'Sketchup modelling' category are representative of what I can do now with the set up I have at home. These were the images I showed first time round along with a few others - minus the house image.
That said, I have progressed since I first posted this thread and I could probably recreate most, if not all, of these images using the software I have now.
The house image is probably the best image I've done on my own and is my most recent piece, though I've had a lot of help from people kind enough to post c&cs on another forum.
I'm actually in the middle of a project at the moment and I'm pleased with how it's turning out. The client seems pleased with it as well.
