Did these recently as gifts for someone. 7"x5".
The 1st 2 did not turn out as I imagined them. I think, perhaps. all the angles and glass were beyond my capabilities. I did work on them a bit more after the photos were taken and darkened the hues on the top balcony walls to make the small sunlight slithers more distinctive.
The recipient is happy with photos, but may not like the real thing as much when the post arrives!

I was happier with the next 2. Slightly different angles of the same roofline.

I don't like it when there is a disconnect with how you imagine a painting, and how it actually turns out. I prefer the ones that happen just as you pictured them! I find sometimes a painting of mine is good, and other ones (like these first 2) look very amateurish. Anyone else have this problem?

I agree that the second pair with the roofline and chimney are better. But no. 2 - the interior with the arched windows - is also interesting.
When you say they look amateurish you have to be more specific or you will not be able to correct yourself. (Since I can’t see what you first envisioned).
Is it the color or value? Is it the transitions in color or value? Is it the edges or abstraction textures?
I’m just brainstorming here to offer some suggestions.
I have posted the photos I worked from. They were all I had and am unable to take more since it is in another country
@GTO, you are correct over the surface. I cursed the cheap canvas on board the whole time, but wanted to use up existing resources and they have been hanging around unused for years. I did not think of filling it in with gesso, Point taken!
@Richard_P, as requested. Sorry I did not think to post them last night.
I am really very grateful.
In terms of giving good critique, this is a great demonstration of how helpful it is to post both the reference and the painting.
I am not au fait with buying, downloading or using apps. I have heard of photoshop, but never used it and have only ever used the paint app that came with my computer when I bought it.
How does one go about installing Paint NET? It looks to be very useful. Thanks.
If you want an image editor equal to Photoshop or Affinity Photo you could get GIMP. I use this often. It's free and does just about everything the others do. You an get GIMP here: https://www.gimp.org/
