Welcome to your second puberty!
Similar to born females, you will experience asymmetrical breast growth. Over time it may become more symmetrical, but your dominant side will generally be larger. Also, being on hormones a short period of time (less than a month), there would be little visible progress, though you may have noticed more subtle changes like thickening under your nipple and breast sensitivity.
Remember it takes *years* for a person to go through puberty, male or female, your development will take a while.
A deep, resonant male voice can be modified to be less harsh, but it will take practice. I personally used the Calperia Adams course and was very well pleased with the results, but it took months of constant practice. There are others, and here is a link to our wiki for voice:
https://www.susans.org/wiki/VoiceBut timbre is only one facet of speaking with a feminine voice. Calpernia touches on these in her course. There are other elements, such as tempo, inflection, and word choice. Listening to other women speak to individuals and to groups will give you some insight to this.
Patience and effort gives the best results.
