This is a difficult step for a lot of people, because the things they're trying to achieve also exist in their head. Imagine you're drawing a bowl of fruit, you know what an apple looks like, you know what a bowl looks like, you know what a banana looks like, so what people do is they ignore the thing they're looking at and just draw what they think the apple looks like. This is wrong, because then you're working hard trying to create the item from scratch, instead of copying what's in front of you.
Look at examples of things you're trying to recreate, if you're making a ships bulkhead, or a warehouse, or whatever then look up images of those, spend time collating them and examining them, and then try to replicate specific parts of them. I went to school to learn how to 'be an artist' and while I'm not great at it, it did help me get procedures and processes down that help in a bunch of areas in life that aren't just art. But then, I spent a couple of years being encouraged to do things on my own with support from teachers. You're essentially learning to 'create art', so look up some stuff on that if it doesn't come naturally, I don't know how easy that would be to find, but it can only help to look.
Also you're encountering something relatively childish that all 'artists' hit, "Why isn't my work perfect" "I see all my mistakes" "it doesn't look like the picture". It happens, just get over yourself and keep working to better yourself and your skills. If everyone could just decide to create something and it came out perfectly first time then there wouldn't be experts at anything, because we'd all be doing it perfect the first time. You'll make mistakes and some stuff you won't be happy with at all, but honestly just get over the childishness of it. You only become good at something through practice.
