As long as you were new !1
Look, i do not beleive that this flash could take a second more than one hour to finish, so do not try to lie.
PROS:-
-yOUR first flash, good step forward
-You stayed dedicated (as you say) and that getting better animations needs dedication.
HOW TO GET BETTER:-
-You need to practice drawing more
-Get a style of your own, that would encourage originality. (an example is the MADNESS series, or Legendary Frog Series) You should find a way of art work that defines you.
GOOD TRY.. HOPE TO SEE MORE.
