As a suggestion,
If one wishes to do Heraldry as a project.
Then I suggest cursory looking up how it is done.
Just "putting stuff" on a shield does not make it Heraldry.

The exact placement of things, the exact types of things, their colours, their postures ..and their interactions with one another on the crest....and soooooo very very much more detail is critical.
It means something...
Every properly done crest or shield were are treasure trove of deliberately executed purpose..
meant to yield books and books of data on that one crest or shield

In the end it speaks volumes and volumes of information.
With one big flag, pennant, crest, shield ...
plainly seen from a distance ..it announced a great deal of important information of those under its banner.
That was the point of Heraldry.

Done without following the Heraldry "rules of engagement" (so-to-speak) in planning out the crest, what you have is not a crest based on Heraldry,
but actually just a ..."picture"..in the most rudimentary sense.

Just as an example ...
In our modern age..that thinks itself so educated, so intellectual, and so deep..
When actually, it is the reverse.
The majority of humanity today have cabbage for brains.
The letter "A" of the alphabet ...is just that...simply a letter to be used as part of a sentence, with zero meaning unto itself, or multiple meanings.
"A" is just a lone "thing" ...like each and every one of the other letters in the alphabet.

Older methods of study such as Heraldry (and even older still studies than that...) do not look at the letter "A" as just a letter.
The colour it is printed in,
the size,
the placement on the crest,
any slight or dramatically noticeable differences in exaggeration
or flourishes
or decorative of the letter,
how they interact with other symbols ...
etc..
Was the vast depth of exactly what that portion of data of the crest yielded.
The rules aren't just "made up", they've been around a long time, most of the said rules predate the art of Heraldry itself, and were adopted by Heraldry...
There are very specific rules to Heraldry, depending upon the rule book...and the exact time period... one follows.
