A piece of the mould, not something to worry about though.
A few air bubbles, otherwise fine. Finecast.
More bubbles... more problematic ones, though totally solvable with more vacuum and faster pouring.
Overview of front.

Edge.
A fine cast.
That's a bit too much finecast that! So the front was the hardest one to get free of bubbles -- to many bubbles to clean up if we make them in greater quantity.
SvaraRaderaI really think that some form of ventsor pits could improve it.

SvaraRaderaThis is true. Make these and the casting may commence.
