Firstly, may I second what @Faith-and-Hope said about not everyone being able to colour as well as you!
That is so correct, I cannot hold a pen/ pencil/ sewing needle/ knitting needles/ whatever normally due to 'things that were done to me' shall we say. So colouring is a massive effort, I do have a pretty colouring book and do manage a bit of colouring sometimes, often the pain just isn't worth it, I'd rather crochet cos I have learned to hold the hook differently.
For many reasons, I often envy those who can put onto paper what they see in their mind's eye and colour it neatly and beautifully, I think we all have that 'something' that we wish we could do and aren't able to!
Secondly, that yarn is simply beautiful!
I always recommend for beginners to start with a single coloured yarn, thicker rather than thinner as it's easier to hold, and to see what your doing, and to see what's happening in images too.
I'm not sure you're having as much trouble as you think you might be. Do you have a pattern or something you are following? Can you tell me where to find it, it's name, or something similar?
What sized hook are you using - should be marked on the handle, and what is the yarn, name thickness/ ply, whatever details on label if you can/ know? It will help me to explain stuff and I like that yarn! 
I'm also wondering how much you already know of the basics of how to do a chain, do single crochet, and so on as you are working on a treble stitch it looks like and that's not a first stitch to learn, so you must know a bit already. Which is a good thing!
So, I use UK terms, but I can often slip up on a couple of them. You use whatever is going to work for you. I learned with UK, Australian usually design and work in UK terms, but often write with both. Try to remember to ask before taking on a project as a couple of stitches can really mess things up if you get the wrong term.
This link describes UK stitches and how to do them one by one, not too overloaded. You can go to video tutorials if you want to from the still images. It will show you in still images how to do the stitch and what it should look like. Love Crochet guide to UK crochet stitches
What if, to keep your thread tidy, we take this over to the Craft Corner? Would that be okay?
Feel welcome to take the discussion over there if you'd like to do that as there will be others who might be able to benefit from such a discussion too.
