I'm fairly new to the photography scene and would love to get into stock photography as a side income while I build my portfolio
I have had a few images rejected for technical issues and would just like to clarity so as to know what I can work on with regards to current gear (which is entry level at best) and from an editing side. Any help would be greatly appreciated
This isn't covered by the technical issue, but if you are able to get over that you should note that #2 will need a property release. #1 will likely need a model release.
the shutter speed seems slow, although it is in focus, it looks blurry. And in the article that adobe has about property release there is precisely an example regarding graffiti. Here is the article: https://helpx.adobe.com/stock/contributor/user-guide.html/stock/contributor/help/property-release.ug...
I hope that helps
In addition to what's been said, be mindful of ownership & copyright. You can't sell another person's likeness or artwork in an image without their written permission.

In terms of entry level equipment, price isn't always an indication of quality. But a good entry-level DSLR with good lenses won't be cheap. Budget accordingly and get what you can comfortably afford while learning. See link below.
Hope that helps.
