bikinimaster ... First of all, welcome to the site and thanks for the compliments.
I can only speak for myself ... but I imagine my answer might be similar to other painters here. Practice .... lots of practice. I've been painting in Forza games for several years now and have just improved over the years by continuing to spend time in the paint booth. My best advice ... just keep painting.
One thing I think has always helped me ... stay active within the Forza painting community and visit the forums often. There are lots of good guide and tutorial threads there and lots of good painters who can give guidance, suggestions and pointers. Another thing that I do that I enjoy and also think helps my painting ... I do a lot of research about actual liveries ... particularly when trying to replicate older ones. I like to make them as accurate as possible with actual race series decals, number boards, etc. It takes more work ... but it's something that a lot of painters won't do and something that can help set your work apart from others.
Thank you for the advice. Iv'e been working on trying to get better at paints it just gives you that feeling off success when you see how many design downloads you have and how many likes you get on paints. To all the PTG guys on here i have downloaded some of your guys work and especially love Stuzi's hellboy challenger hellcat. You guys have probably inspired more than just me to get into the world of painting.
Hi Bikinimaster, thank you for the positive comments! As Wildcat said, practice is how we got as good as we are, but that doesn't mean you can't create you're own works of art. Liveries don't have to be hugely advanced to be cool, but the number one thing I would tell a beginner who was looking to improve - attention to detail. That cannot be stressed enough. Make sure that if it's there, in the image you're using, it's there in the image you're painting. Whether that's a logo or a portrait, same thing applies.
Hope that helps. Feel free to drop in my stream later tonight, 9pm UK, where I'll be painting and answering any questions.
