I'd have to say I like the first one, although a few suggestions. As mentioned above, the color is a bit too musky, try making it a bit less saturated, and adding a tint of a little cooler color like green or blue, it'll make it look much better and cleaner on your channel. I'd also suggest making the lines a little lighter as they seem a been too intrusive right now. The doodles around the title seem fine, I'd suggest pulling them inwards a bit more if anything to make use of the negative space, you seem keen on keeping them closer to the edges. As for the title itself, I like how the doodles that are touching it are significantly lighter, it keeps the emphasis on the title.
