(Help no longer needed) Please help me get better at development

Update: I no longer need suggestions, thanks to both of the people who gave suggestions

Hello. I am a noob developer who wants to try and make a showcase. I need some tips and recommendations for some things.
First, what programs are good for making thumbnails?
Second, what is the best program to make textures? (I also need to know how to make detailed textures, any good tutorials on how to make some?).
And last, how do I make a good showcase?

About my showcase

Image above - A screenshot of my current build of my showcase.
My structure is a futuristic city (Not all structures made yet), made to show what I can do and look the best that it can.

Thanks for taking the time to read my post, and please have a nice day.

First, what programs are good for making thumbnails?

Blender for GFX’s (search up Roblox Blender Gfx on youtube for tutorials. Then use getpaint.net (AKA paintdotnet) for editing.

Honestly you’re better off either a) searching up free ones or b) taking photos. If you have a graphics tablet/ipad pencil and know how, you can illustrate one yourself, I’ve done it.

And last, how do I make a good showcase?

Build every day, if you don’t feel motivated, decide on ONE TASK you want to do, do it, and call it quits for the day.

Blender isn’t always needed.

3D Viewer/Builder, Figma (or Lunacy).
