okay cleaner model ...if you look at dragon ..see how lines all flow in one direction and all together ...I am not at home to show you more or what yours looks like ...
your dog ..has some lines that dont go all the way or four where it has four sides ... some of yours has more than four ..it has five or three sides ..it is not good practice to have those cause will deform how it looks when you convert or stop you from converting ...
is that better ?
here look at this thread
see how frog looks and look at yours ...see diffference
all have four sides and just cleaner looking, especiallly where fingers attached and arm and legs attach to body ..
congrats on figuring it out and any questions we are more than happy to help
