Several things I see. Not trying to be critical, only helpful.

1) Undercut at the top. You need to pause at the top to fill completely. You are swiping down before you fill the top.
2) I assume you are using DC, or at least you should be...but 90 amps is probably a little too high for 3/32 7018in this position. You need about 75.
3) Slag on the top pass looks like its being rolled into the toes. Watch your rod angle, and arc length and move steadily.
4) PUSH your rod into the gap on the root. (IF you are using the hobart you have in the sig, it may just not be able to do it) Step it...Pause until you melt it through. Use a welding rod with the flux broke off to provide the gap. Bend it into a U shape and insert it into the gap. Tack it all the way around. 6011 is ok, but 6010 will cut out the key hole better.
5) Watch your restarts. You have to start in front of the crater, and long arc back to the orginal pit. Let it start and fill the crater to make a smooth transition. Its one of the hardest things I think most people have to learn to do when starting out welding.
