Im currently a student working on stylized texturing for a class. I am having quite a bit of trouble with it. So if anyone can please point me in a good direction of how to quickly learn this texturing process? Or how what one tackle a project similar to this? Plus, I would also like UV layout advise as well please!
Below are images of my current projects:

You also seem to be rendering it in a 3D viewport of a 3D package instead of a game eengine or real-time rendering engine that can do beauty shots. Download Unreal, unity, or Toolbag and get your beauty shots done there.
So i think your uvs are alright there's a lot of empty space that maybe you could expand your sets and fill it up, I'm not super great a uv advice.
I think your wood texture on the sheild is getting there i think you need to add some highlights and edge lighting to help add some contrast and make the weapon pop. On metal parts dont be afraid to add the white reflections and use the colour dodge layer to help it beam and shine, it'll help your metal stand out as a different materail, which i think is a big problem your having is that all your materials look the same.
I don't know what your references are like but when I do gold i usually make it very yellowy/orange colour (much more saturated), for metals i usually add a blue hue as you generally don't want it to be grey.
I think your also missing a lot lighting information on here, theres no real light on anything and not much if any shadow/AO, make sure before you start painting you essabilish your light source
You clouds sword at the top is farrrrrr to dark, I know the sword is a dark grey but you've painted it almost black. I wouldn't hand paint anything black unless it was in very dark shadow. I think again your gold is looking a big murky and not very saturated.
I'll link you too a very helpful tutorial he'll take you though how to hand paint a whole environment I found and still find it very useful

I hope this helps abit
Right now, it looks like a mix of both but I look at your metal blade in the second image and it has pre-painted highlights. You can't have any shadow or specular information in the diffuse when you go and light it.
And as a word of warning about class projects, you need to spend more time outside of the actually assignment time to gett it portfolio ready. It's been rare to see homework as portfolio worthy assignments on Polycount and other portfolio's we've seen. The one's that are good are the ones that had more time put into them past the grade.
