Really nice one man, not an expert on painted textures but I've managed to pick some stuff up by studying other people's work. I think you need to crank the values a bit more, make 'em pop, it's my personal preference when making stuff like these. Try too zoom out from your object in the 3D view and see what elements…
Pretty damn fine for your first try 2 things I'd change: - The damage. You could use some more nicks and dings on the blade itself, as well as a colour change where it connects to the wood (rusty orange or maybe a greenish blue). I think that could really make this pop :) - AO. Add some cool dark tones where things connect…
Its definitely a good first try at it! Wood is definitely one of the hardest materials to master in hand painted textures, it is up there with sand and tileable gravel/pebbles (any ground texture is a challenge due to the player always looking at them, so the level of quality has to be higher). As said above, the challenge…
