Hello there, FinallyHere
Yes! Read as many tutorials as you can! They help you to get better and learn new techniques which you can apply into all of your images Even the pros, such as myself......still read them. I read about 5 per week. It's like school. You study so you can get better. Tutorials achieve the same effect.
The reason you feel like you aren't great, is because you have just started. Different people come into PDN with different levels of experiences. Don't be too alarmed if you aren't getting it. Just keep trying until you do. Opening up Paint.Net, and playing with all the features is all a good way to learn too Very quickly you will get it, and you will be on your way of becoming a great artist
To become "famous" like Ash, Jake,THS, Simon, and the others, you have to do something great. They have all been with Paint.Net Forums for ages, and have done something magical for it. But for now, just regularly posting, creating a gallery with your work, and being an active member is all you should really strive to do
If you ever don't understand something, want help, or just advice, we are right her for you
