MakerFarm Prusa i3v 10" - And So It Begins!

Not bad for first prints. Are these with Simplify3D or some other slicer? What are you using for the source of your settings?

First, I assume you're printing with a skirt. Does the skirt always have the zig zag shown in the vase picture? If so, that's a problem. One similar case was due to the x-carriage wheel mounting bolts rubbing on the large gear. The last picture in this post of my build thread highlights what to look for. If the zig zag is unique to the vase, it's just a replication of the bottom layer outer edge of the vase.

After that, I'd suggest posting a picture of how your first layer looks before paying much attention to the rest of the prints. Without seeing the bottom of a print, it looks like there are issues to work through regarding either the amount of nozzle-to-bed clearance or nozzle temperature.

Have you calibrated your extruder? That's just another thing you want to do before spending much time scrutinizing print results.

The rough sides on the vase could be any combination of slightly high on extrusion, not enough retraction, or too high of a hot end temperature.

The small robot can be tough as an initial print. The "underarms" are especially tough since the design leaves them supported. At some point you can add a print cooling system that'll help, but expecting unsupported loops like that to remain perpendicular is always going to be tough without adding support. I personally don't like trying to add support under the arms since it will have to rest on the feet in order to be where the support needs to be. When I'm printing the robot as a test or as a giveaway, I try to be nearby when the underarm starts to print, and slip a putty knife under loose strands to simultaneously prop them up and harden the soft filament.
