This looks pretty good to me, though I don't know why you'd weave with a 7018?

I don't "whip" 7018 rods. I lay them in and burn them. I leave the whip for 60xx

I see a lot of weld, as long as you feel confident you don't have voids below, it looks good.
Trying to learn TIG as well.
Outside corner Vertical Up
1/4" Plate, 150Amps, 3/32" 2% Lanthanated, 3/32" ER70S-6
Should have used more filler and more heat i think...

You say this was welded uphill? It looks like downhill to me from the direction of the freeze lines. My opinion is that whenever you weld downhill with TIG, penetration is at risk because you're asking the puddle to defy gravity. When I do TIG downhill on thick metal, I feed the rod from behind the torch, and pull it forward, step back, feed, pull forward. Kind of the opposite of aluminum feeding.
First attempt at Aluminum
Unknown grade of plate. Cut in half and did flat butt weld.
3/32" 2% Lanthanated, 3/32" 4043, 120Hz, 30%ish cleaning
I've done more since then and getting better at it. But still not great.

You don't indicate thickness of plate or amps used, so the only comment I can make is, for a first try, you did well. Try traveling farther and dabbing less. Equal travel distance to rod diameter is my rule of thumb.
There's a trick you can also try to employ: if you use a pyrex cup, you can see better. But when you add filler and move forward, you will notice the puddle sort of "suck in or recede". Thats when you know you've gotten the penetration you seek and its time to add wire and travel again.
Attempted razor blades, heat built up too fast i didn't move fast enough and didn't let out on the pedal fast enough. I didn't have a chill block either. It was sitting on 1/8"x6"x6" steel plate.

I didn't even bother to look. I will simply say, Bravo for trying regardless of your success!
