Does anyone know how I can start and get better at drawing pictures and images on computers? any starter tips?

Explanation:

If you don't have a digital art tablet yet, that would be a good place to start. Newegg is a great place to look for cheaper tablets, just make sure the computer you're planning on using fits the specs needed for the tablet you want to get.

Getting a decent drawing software is also important. Photoshop and PaintTool SAI are often recommended, but they're kind of expensive and free alternatives such as MediBang, FireAlpaca, Krita, and MyPaint exist and work just as well.

Actual skills wise, get used to using references and don't be afraid to draw inspiration from or reference other works. Places like Pexels and Reference.Picture have great photos that cover almost everything from landscapes to people to animals.
