Writing a Sonata/Sonatina in modified classical sonata-allegro form?

[sumpianodude]

so i'm writing a sonata/sonatina(just started, no idea how long it will be), and my intro is couple of slow pained arpeggios(more than a couple- 18 measures!), with my first theme only (a rather lively) 5 measures(it goes from 4/4 in the intro to 4/4 in the first theme with a 12/8 pulse of triplets). i have a bridge with a small idea which lasts a measure before repeating itself and taking 3 more measures to modulate from C# to f.
so my question:
should i try to cut down my intro or try to increase the length of the the first theme or just write a ridiculously long second theme or even just make my intro my first theme and make my current first theme part of the bridge...?
any thoughts?

As a fellow composer, I would recommend developing the first theme as much as you can, then match it with a contrasting second theme ...

If it's already maxed out, go on to the second theme. If there's no more you can do with it, by all means ignore my advice. But what separates the wheat from the chaff, composer-wise, is the ability of the composer to develop a theme as many ways as possible, then have it make sense in the context of an entire piece.

another question to tag onto this thread:
what is your opinion on revising peices? if you were to write a peice, then add a theme smack into the middle, and have another transition into your next part, what does that do to the transitions and how "natural" they sound?
also, fan i thought development of the themes went in the... development section (no surprised there )

Without hearing the work it's hard to comment. If the new theme enhances the work without changing the general mood and structure, I would say it's fine. The only thing you can do is use your ear and play the piece all the way through. Does the new theme improve the work? Or does it create more problems?
