Loud , Clear , Ringing BELTY Chest VOICE

Hello. I'm from India and I'm a tenor. I finally built a very ROCK SOLID Chest VOICE upto C5 on vowels AH , EH , AW , AE , EE , O , Ooo using scales like 5 tone scale , octave arpeggio , 9 note scale , circular major 5th and circular major 9th respectively and using concepts like Soft palate lifting , support , posture , vowel modifications (all found in Ken's Free YouTube videos , live streams and written on the website). Also can establish a clear strong head voice/strong reinforced falsetto on G5 and can bring it down upto C4 on all vowel sounds. Still I don't have what it takes. I don't have the agility or dynamic control in singing songs. That's the issue I'm facing.
Goals :-
# - Broadway Voice
# - David Phelps Nessun Dorma style of singing
# - Arnel Pineda (Journey) Style of singing
# - Myles Kennedy type of vocals found on his early alter bridge albums One day remains and Blackbird.
My abilities currently :-
# - CHEST Voice (Full Voice) = C3 - C5
# - Head VOICE (Strong Loud Reinforced Falsetto) = G5 - C4
Problems :- Whenever i encounter HIGH notes in songs , in order to be connected, i tighten my abdominals to get the power and Yell up (but no resonance) or if I let go i flip into falsetto. My voice sounds very resonant , CLEAR and ringing while doing scales on chest coordination but in songs that stay in G4 - C5 range I sound SHOUTY with no resonant quality like the brightness/ping to it but while doing scales using Vowels in full voice , I have that Cord Closure , Bright Ping and CLEAR Belty chest quality upto C5.

Comments
If you can do all that in your scales now, it may still take some years of training to gain full control in a song. I've been practicing singing now for over 2 1/2 years. I still think it will take that amount of time before I can comfortably sing what I want.
Treat scales as a way of stretching your voice and range, but getting to the top of your range in scales is a way of staying comfortable singing songs a few notes below.
having said that, i think you are on a good track. are you considering getting the course? it is obviously the safest bet to get all the details sorted and perfecting your technique
Saving the mods till later is good, but not so much that you go past the point where you should have used them.
