First things first. Your Light team is good as is and unless you are a dedicated Light lord with an excellent grid, there is no point in using Miracle Ticket for another Light Hime. Diana covers A frame (15%) for now while Tsuku has Light resist down (15%) and your soul covering the B frame with Sniper Shot (20%), help you reach debuff cap.
Besides, Light gets some strong additions which introduce an offensive style in SSArtemis and later on with Michael's Awakening (refer Bear's guide for more info).
To be honest, your Dark team just has Satan and dark gets some great himes ahead especially Pluto. I wouldn't suggest investing in Dark at the moment.
Your water team looks solid and I suggest waiting for Ashirat during next Miracle Ticket if you wish to improve water.
For now, I would suggest looking to improve fire so you have atleast 3 strong elements. You have DPS in Svarog and Ares and both are Awakenable (Ares incoming with next event). But you are lacking debuffs and utility outside that. I would suggest using your Miracle Ticket on Mars since she is core for fire. She has a good buff and helps you reach debuff cap with her Fire resist down debuff. Also against bosses like Wind Rags, even if she can't debuff, that same ability becomes a 6.5x multiplier nuke. Lastly she has a Dispel as well.
All you are lacking for your fire team is Mars and Amaterasu and I feel Mars is more important at the moment.
In the end, that's just a suggestion. If you feel you don't wish to invest in fire and improve elsewhere, it's your call.
