Thanks for your comments...
I actually meant these images to be more on the sketchy side but the people cutouts really didn't help that as they bring a photo touch to it that competes with the sketch.
Otherwise I like the mix between the sketchy feel and some GI/irradiance effects.

sepo, the trees I think you are talking about are actually a component I got from the warehouse. It is the "arvore 3" by Gabriel Felin. I think this is one of the best trees out there for fill in trees at a small memory footprint. All I did is explode the leaves and make them cast shadows, podium follows the transparency for a nice detailed shadow (unlike SU). I love the way these trees render.

Liam, I used podium with some hidden line overlay and a little tweak in lightroom.
I see what you mean about the rough car in the front. I thought that the mix between sketch and podium will look interesting and it did in the other shots. It's just that maybe this car became a little too prevalent. I actually like the cartoony feeling overall and that's why I overlaid the lines (in PS with a multiply) so it feels a little less rigid.

Hello everybody,
I am seeing so much talent here it seems like the right place to look for ideas and just learn new things.

First off, thank you everyone for sharing your knowledge and I hope I can give back as much I could so please ask me if anything.
I wanted to introduce myself by posting a few images that I just finished.

This job is a community center (used to be an old firehouse)in the south side of Chicago and the character of the renderings was inspired by Solo, whose images I stumbled upon once browsing the internet and this is how i found this website. He must be one of the very best talented people you have on this forum.
So thank you solo!

Would love to get your comments and suggestions.
Also if anybody has found some different lo-poly people that look good let me know. The 2d ones just don't look right from a birds-eye view.
